Thx for answering the questions.
As a speaker balancing the slide (amt of text) to what is presented
verbally is difficult.
I personally try to minimize text and maximize verbal but that is
useless if the person didn't hear the talk. Using the 'notes' feature
and publishing slides + notes is something I think about doing.
My favorite talks are slides w pics that allow u to think as the
speaker talks but the slides are worthless after the fact!
